Toall whom it may concern:

.Be it known that I. CARL H. BIssnLL, of Syracuse, in. the county ofOnondaga and State of :New York, have invented a cer- Cluster Lamp-Socket, of-which the following is a specification.

This invention relates to incandescent electric lamp sockets and one ofthe objects thereof is the production of a cluster or plural lampsocketwwhich is particularly .Other objects will appear throughout thespecification.

The invention consists in the combinations and constructionshereinafterset forth and. claimed.

In describing thlS invention reference. is had to the accompanyingdrawing in which like characters designate corresponding parts inalltheviews.

Figure 1 is a plan of one form of my lamp a sectional view on line A AFig. 1. v Figs. 3 and 4. are sectional views taken on the plane of lineBeB, Fig. 2, the-connection for. a drop light being ShOWIlzlH Fig. 3 andfor a switch in Fig.4. Figs. 5 and v6 are opposing face views ofithebodyx and-cap 1 of the lamp socket.

This cluster-lamp socket comprises, gen- ,erally, a. hollow bodyopenatone side,.a plurality.- of sockets associated with thebody, sideofthe body lamp contact terminals in the sockets, conductors withimthebodyconnecting like terminals of the sockets and .feed or plug terminalscarriedbytthe cap and electrically connected respectivel .totheconductors. In the illustratedmeml iodiment of my cluster socket,

.mea-ns..is provided by which another elec- .trical appliance may beconnected in series with the conductors'between one of the feed orplug-terminals and said conductors if the switch, or may be com necteduinmultiple-with the conductors, if the; appliance is a -.lamp.

25 is a removable link or clip electrically connecting the pair ofscrews 18, 19, said clip at one end extending under the head of thescrew 18 and at its other end extending under the head of a screw 26threading into the hollow screw 19.

As thus far described when the plug terminals are turned into a feedsocket the current will pass'to or from the outer plug terminal 10through one of the lugs 15, screw 18, link 25, screw 19 and conductor24, yoke 7, terminals 5 through the lamps to the terminals 6, conductor8 and central plug terminal 9.

27 and 28 are the opposite arms or wires of the branch circuit adaptedto be connected in series between the plug terminals and the lampterminals, or to be connected in multiple with the lamp terminals. Whenthe arms 27, 28 of the circuit are connected in series with the lampterminals, a snap switch is attached thereto for making and breaking thecircuit to the lamp terminals, 5, 6, and one of the arms of such circuitas the arm 27 is connected to one of the binding devices of the pair ofterminal members or screws 18, 19 as the binding device 23 of the screw19, and the other arm 28 of the branch circuit may either be connectedto the other binding device 21 or the screw 18 when the link 25 isremoved, or may be connected to a binding device 29 projecting from theconductor 8. In the latter case the branch circuit is connected inmultiple with the lamps and is designed to be connected with anincandescent drop lamp. The branch circuit extends outwardly through theopening 80 located between the sockets 3. In order to relieve thebinding devices 21,, 28 and 29 of the weight of the wires 27, 28 andappliances, the wires are looped through holes 31 in the cap.

This lamp socket is particularly advantageous in that it consists of butfew parts, which are easily assembled, and in that the parts are easilyaccessible, and further in that-either a drop lamp or a snap switch maybe used in connection with the socket.
